Hi Stuart,

I think, I know what you want to say.

The reality of a divider after reset is:
Stepnumber  1 2 3 4 5 6 7 8
      clock .1.1.1.1.1.1.1.1.
         /2 ...11..11..11..11
         /4 .......1111....11

But you want

Stepnumber  1 2 3 4 5 6 7 8
      clock .1.1.1.1.1.1.1.1.
         /2 .11..11..11..11..
         /4 .1111....1111....

And the best thing for percussion triggering would be

Stepnumber  1 2 3 4 5 6 7 8
      clock .1.1.1.1.1.1.1.1.
         /2 .1...1...1...1...
         /3 .1.....1.....1...
         /4 .1.......1.......

This would require a lot of hardware if it would be realised with 
standard logic chips, but should be a easy job with a PIC.

A long time ago I already asked in a poll for a multi purpose 
masterclock module.

Should have

Internal Clock,

MIDI-Clock-In/Out,

DIN-Sync-In/Out,

16th, 96th, 192th Clock In/Out,

Triggers out like in the last example above, with highest rate as 32th 
(if the master clock is fast enough) and longest should be 2 bars (in 4/4).
The trigger outs must be available all at the same time (not a single 
out with a rate selector).

Additionally the modul should provide a swing factor (but not as rough 
as in the jomox Xbases); this should be possible for all clock modes 
with the exception "slave of 16th-Clock in".
